Further to 'OK, but...' Rated 1 out of 5 stars
I don't understand your failure to understand my complaint. Your add-on promised a 360kbps download but I got one at roughly double that bitrate. I didn't play the video in the Youtube player at all. And Get Info on my computer confirmed the file size as 120MB approx.
The one-star rating is for your reply to my original review.
360p is not a bitrate and doesn't mean 360 kbps. 360 is just the number of vertical pixels, the resolution of the video.
1080p = 1920 x 1080
720p = 1280 x 720
Please read the extension's description and you'll find all the resolutions, includng 360p. The most common resolutions for 360p are 480x270 and 480x360. And don't tell me that's a misleading name because it's the name used by YouTube (try clicking the setting icon from the player).
